1	hanging drop		292	CRYSTALS WERE GROWN AT 19C BY VAPOUR DIFFUSION IN HANGING DROPS FROM 1.0M AMMONIUM PHOSPHATE, 0.1M SODIUM CITRATE PH 5.0. PROTEIN STOCK WAS BACE MUT46B BATCH XII 8.45MG/ML IN 10MM TRIS-HCL PH 7.4, 25MM NACL, WITH A 2.5-FOLD EXCESS OF BMC023 ADDED FROM A 25MM STOCK SOLUTION IN DMSO (2% DMSO IN DROP). CRYO-PROTECTANT WAS 1.2M AMMONIUM PHOSPHATE, 0.1M SODIUM CITRATE PH 5.0, 25% GLYCEROL, 0.5MM BMC023, 2% DMSO.
